Madison, Ms
Has anybody got any good data for a 208 or a 178 amax with H110 for a 10.5” sbr .300 blackout. I’m running a SAS ARBITER can and have got it cycling good after fooling with the gas block and they are definitely subsonic but haven’t had time to really sit down and develop a “load”.
The load I did come up with was 7.8 H110 208 amax but was getting a lot of vertical. Was using CCI 400 primers. And my coal was 2.260”. Should I seat deeper? New to the sub game and could use some help. Thanks. Aimsmall

My load for my 10.5” upper suppressed: h110 10.0gr cci 400 208 amax coal 2.25” runs right about 1070fps. Wolf SRM primers same load will give 1035fps....
